Industrial Strength Wireless Ethernet for Entertainment Applications from

Goddard Design Company


Discontinued Product

Goddard Design was the first to do wireless lighting data. Our systems have always been based on the best available industrial communication technologies. With the advent of lighting sent over Ethernet it made practical and economic sense to use wireless Ethernet technology, Hence our trail blazing WOW product was replaced bE-link2.4 connector side viewy a wireless system using our DMX-LINK Art-Net product and 80211 bridges.

However, in some mission critical applications 802.11 products are neither rugged or reliable enough for the small scale war that is theatrical touring, The very popularity of 802.11 is one of the problems. Many a venue now has wireless Ethernet in the front office. Interference and much lower than expected thru put is a real possibility.

We felt a need for something more for our rental division and for our customers who have mission critical wireless applications. It does not matter if they are running our DMX-Link product or PathPorts, you need a robust product that can work in an environment that already has too many 802.11 products running!

We are happy to be able to offer E-Link2.4. This is the latest in high speed/long range industrial wireless networking product from an established leader in spread spectrum wireless products since 1987. The E-Link2.4. is THE Ethernet bridge for theatrical applications.

E-Link2.4 utilizes fourth generation proprietary frequency hopping technology. Major industrial powerhouses including Siemens and GE already use these techniques - why shouldn't entertainment lighting?

E-Link2.4 products offer 840Kbps of usable data throughput, either point-to-point, or multi-point. This ensure errorless data via CRC error checking combined with outstanding range, coverage, and link reliability.

E_Link with detachable radio unitThe E-link2.4/X puts the radio in a NEMA 4X remote assembly that can be mounted up to 300 feet from the Ethernet connection. This allows optimal radio placement without the need for long RF cable runs.

Goddard Design is pleased to be able to offer a truly professional grade product at a price considerably lower than some other ‘customized’ theatrical units.  The E-link2.4 is  FCC certified and CE marked.
